Description

The present invention relates to a soot treatment device that pulverizes soot and flows it to a drain pipe, and more particularly to an impeller provided on the lower surface of a rotating plate of the soot treatment device.

In the conventional slag processing device, garbage such as garbage thrown in from the sink outlet is put together with water onto the rotating plate at the bottom of the crushing chamber, and crushed by the centrifugal force of the rotating plate and the hammer provided on the rotating plate. Further, it is shredded by a fixed blade around the rotating plate, dropped into the discharge chamber below the rotating plate, and allowed to flow out to the drain pipe. (For example, see Patent Document 1 and Patent Document 2)
Further, in order to accelerate the flow of water and crushed material from the discharge chamber below the rotating plate to the discharging port, it has been proposed to provide an impeller on the lower surface of the rotating plate. (For example, see Patent Document 3, Patent Document 4, and Patent Document 5)
In addition, since the fiber of the ridge is difficult to cut in the processing with a hammer or a vertical groove fixed blade, a cutter plate that closes the bottom of the vertical groove close to the lower surface of the fixed blade is attached to the rotating plate. There is something. (See Patent Document 6)

However, dredging equipment that does not have an impeller requires a large amount of water to discharge dredging that has fallen into the discharge chamber only by the flow of water, and the bottom of the discharge chamber is inclined toward the discharge port. It was necessary to provide a flinger surrounding the bearing portion so that crushed soot and water would not enter the bearing portion of the rotating shaft penetrating the center of the chamber. In addition, in the dredge processing apparatus provided with the impeller, a plurality of blades are provided in the radial direction on the lower surface of the rotating plate. How to attach the blades is integrally formed with the rotating plate as shown in FIG. However, there is a problem that the blades of different parts are individually fixed to predetermined positions of the rotating plate by rivets, welding, etc., and the manufacturing work is complicated and the manufacturing cost of the rotating plate is high.

Also, when attaching a cutter plate close to the lower surface of the fixed blade to the rotating plate, the rotating plate and the cutter plate cannot be assembled and removed when the fixed blade is attached to the casing. Since the rotating plate cannot be taken out from the rotating shaft unless it is removed from the casing, there is a drawback that the assembly and disassembly is troublesome.

For this reason, the present invention provides a crushing chamber for crushing the thrown slag, a rotating plate that forms the bottom of the crushing chamber, a fixed blade provided around the rotating plate, and dropping the crushed soot from the periphery of the rotating plate. In a dredge processing apparatus provided with a discharge chamber and a drive motor for a rotating plate below the discharge chamber, and provided with an impeller for accelerating the flow of water and crushed material falling into the discharge chamber, bearings in the discharge chamber are provided on both sides. An abutting plate having straddling side plates is attached to the lower surface of the rotating plate so that the side plates face the lower side of the discharge chamber, and both end portions of both side plates are formed in the shape of an impeller.
In addition, an extension that protrudes from the rotating plate and close to the lower end surface of the fixed blade is provided at both ends of the abutment plate. I try to cut it.

In this way, the present invention is provided with a backing plate having side plates on both sides and attached to the lower surface of the rotating plate, and both ends of both side plates are formed as impellers, so there is no need to attach the impellers separately. A plurality of impellers can be configured simply by stacking the contact plates, and the effect of simplifying the production can be obtained. The contact plate can be used as a reinforcing plate for the rotating plate.
In addition, by providing an extension that protrudes from the outer periphery of the rotating plate and faces the lower end surface of the fixed blade at both ends of the backing plate, it will drop into the discharge chamber at the edge of the extension and the lower end of the fixed blade. By cutting the ridges, the long fiber can be prevented from being entangled and the tubs can be smoothly discharged. Furthermore, if this extension is made to be smaller than the vertical groove width of the fixed blade and protrudes to the length that enters the vertical groove, and in the case of a plurality, it is set to an integral multiple of the groove pitch, so that the fixed blade is not removed from the casing. Can be attached to and detached from the rotating shaft to facilitate assembly and disassembly.

A crushing chamber for crushing the introduced soot, a rotating plate forming the bottom of the crushing chamber, a fixed blade provided around the rotating plate, a discharge chamber for dropping the crushed soot from the periphery of the rotating plate, and a discharge chamber In the soot treatment device provided with an impeller for accelerating the flow of water and crushed material that has fallen into the discharge chamber, the bottom surface of the rotary plate is directed downward on the both sides of the discharge chamber. A backing plate having side plates is provided in an overlapping manner, and both end portions of both side plates are formed as impellers. Moreover, in order to cut | disconnect a fibrous wrinkle efficiently, the extension part which protruded from the rotating plate and was made to adjoin to the lower end surface of a fixed blade was provided in the both ends of the said contact plate.

FIG. 1 is a side sectional view showing an example of a soot treating apparatus embodying the present invention, and FIG. 2 is an exploded view of a rotating plate portion. 1 is an inlet, 2 is a crushing chamber, 3 is a rotating plate provided at the bottom of the crushing chamber, 4 is a reinforcing plate attached to the lower surface of the rotating plate 3, and cuts and raises the crushing hammer 5 to form a groove 6 in the rotating plate 3. It protrudes from. 7 is a fixed blade surrounding the rotating plate, 8 is a discharge chamber below the rotating plate, 9 is a discharge port, 10 is a motor for rotating the rotating plate, 11 is a rotating shaft thereof, and 12 is a bearing portion of the rotating shaft.
Reference numeral 15 denotes a backing plate formed in an angled shape that overlaps with the lower surface of the rotating plate 3 together with the reinforcing plate 4 and opens downward. The center portions of the side plates 16 on both sides straddle the bearing portions 12 in the discharge chamber 8, Is formed on the impeller 17. Reference numeral 18 denotes a cutout hole for adjusting the resistance of the impeller 17 with water.

The backing plate 15 is bent on both sides of a stainless plate punched into a required shape to have side plates 16, both ends of the side plate 16 are formed in the shape of an impeller 17, and are attached to the rotating shaft 11 by being stacked under the reinforcing plate 4. ing. Therefore, it is possible to provide a plurality of impellers 17 simply by attaching the backing plate 15 in an overlapping manner. The motor 10 is driven to rotate together with the rotating plate 3, and the crushed soot and water that fall from the crushing chamber 2 to the discharge chamber 8 are removed. The impeller 17 can be sent out to the discharge port 9 while being pressed against the outer periphery of the discharge chamber 8.

In addition, outside the side plate 16, the crushed soot and water that have entered the central portion of the discharge chamber 8 are blocked from entering the bearing portion 12 by the side plate 16 that surrounds the bearing portion 12, and crushed by falling between the side plates 16. Since the spear and water are strongly pushed out by the impeller 17 provided close to the outer periphery of the discharge chamber 8, there is no need to provide a flinger surrounding the bearing portion 12, and the bottom surface of the discharge chamber 8 is inclined toward the discharge port. Therefore, the discharge chamber 8 can be simplified in shape.
The side plate provided with the impeller may be attached to both sides of the flat surface of the backing plate by welding or the like, but is preferably formed by bending.
